Caffeine and modafinil have very different effects. Modafinil just makes me alert and wanting to be in action. I don't feel tired, but I can sleep if I want to.

Caffeine and modafinil have very different effects. Modafinil just makes me alert and wanting to be in action. I don't feel tired, but I can sleep if I want to. Caffeine is much harsher, and too much makes me nervous. And after a while, I'm tired, yet still too buzzed to sleep.

Try combining caffeine with l-theanine. The theanine attenuates the jittery edge and really seems to improve focus for me.
